My view on this has always been: The models are assuming that it exists at a large scale to solve for the climate problem, so we have an obligation to do the instrumental work to figure out if that’s possible to begin with.

We’re starting to do that, which I think is very good. The challenge with removing CO2 from the ambient air and putting it... See more

Around 2014, a team of Stanford scientists hired by Google to research green energy technologies came to a startling conclusion. “Even if every renewable energy technology advanced as quickly as imagined and they were all applied globally,” they wrote, “atmospheric CO2 levels wouldn’t just remain above 350 ppm; they would continue to rise...

The interest in CDR is growing. Why is this? Because it is becoming apparent that we are not going to reduce our CO2 emissions fast enough to avoid surpassing the 2°C goal. As a result, if we exceed the carbon budget associated with 2°C warming, CDR technologies could remove CO2 from the atmosphere to bring the carbon budget back into balance.
